I agree.  That's how you should do it now.  I was wondering why and when it 
changed.  It certainly seems more convenient.  It strikes me as being similar 
to Sun's method of having kernel options being run-time modified instead 
compile-time modified.  Is this where things are headed in kernel land? 
Googling on the topic has not yet turned up what I am looking for.

This quest began with the LDP howtos.  Could it be that the LDP is falling 
_way_ behind the kernel development?  The PPP HOWTO talks about 1.x and 2.2.x 
kernels but not 2.4.x.  There's no mention of /proc/sys/net/ipv4/ip_forward 
in the doc.
